Method Swizzling
Monkey patching is a technique used to dynamically update the behavior of a piece of code at run-time. A monkey patch (also spelled monkey-patch, MonkeyPatch) is a way to extend or modify the runtime code of dynamic languages (e.g. Smalltalk, JavaScript, Objective-C, Ruby, Perl, Python, Groovy, etc.) without altering the original source code. Etymology The term ''monkey patch'' seems to have come from an earlier term, ''guerrilla patch'', which referred to changing code sneakily – and possibly incompatibly with other such patches – at runtime. The word '' guerrilla'', nearly homophonous with ''gorilla'', became ''monkey'', possibly to make the patch sound less intimidating. An alternative etymology is that it refers to “monkeying about” with the code (messing with it). Despite the name's suggestion, the "monkey patch" is sometimes the official method of extending a program. For example, web browsers such as Firefox and Internet Explorer used to encourage this, although ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Method (computer Science)
A method in object-oriented programming (OOP) is a procedure associated with a message and an object. An object consists of ''state data'' and ''behavior''; these compose an ''interface'', which specifies how the object may be utilized by any of its various consumers. A method is a behavior of an object parametrized by a consumer. Data is represented as properties of the object, and behaviors are represented as methods. For example, a Window object could have methods such as open and close, while its state (whether it is open or closed at any given point in time) would be a property. In class-based programming, methods are defined within a class, and objects are instances of a given class. One of the most important capabilities that a method provides is ''method overriding'' - the same name (e.g., area) can be used for multiple different kinds of classes. This allows the sending objects to invoke behaviors and to delegate the implementation of those behaviors to the receiving o ...

Indiana Pi Bill
The Indiana Pi Bill is the popular name for bill #246 of the 1897 sitting of the Indiana General Assembly, one of the most notorious attempts to establish mathematical truth by legislative fiat. Despite its name, the main result claimed by the bill is a method to square the circle, although it does imply various incorrect values of the mathematical constant , the ratio of the circumference of a circle to its diameter. The bill, written by a physician who was an amateur mathematician, never became law due to the intervention of Prof. C. A. Waldo of Purdue University, who happened to be present in the legislature on the day it went up for a vote. The mathematical impossibility of squaring the circle using only compass and straightedge constructions, suspected since ancient times, had been rigorously proven 15 years previously, in 1882 by Ferdinand von Lindemann. Better approximations of than those implied by the bill have been known since ancient times. Legislative history ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adblock Plus
Adblock Plus (ABP) is a free and open-source browser extension for content-filtering and ad blocking. It is developed by developer Wladimir Palant's Eyeo GmbH, a German software company. The extension has been released for Mozilla Firefox (including mobile), Google Chrome, Internet Explorer, Microsoft Edge ( Chromium based version), Opera, Safari, Yandex Browser, and Android. In 2011, Adblock Plus and Eyeo attracted considerable controversy over its "Acceptable Ads" program to "allow certain non-intrusive ads" (such as Google AdWords) to be allowed under the extension's default settings. While participation in the whitelisting process was free for small websites, large advertising companies were required to pay a fee in order for their ads to be whitelisted. Background The original version of Adblock (0.1) was written as a side project for Firefox by Danish software developer Henrik Aasted Sørensen, a university student at the time, in 2002. It hid image ads through use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NoScript
NoScript (or NoScript Security Suite) is a free software extension for Mozilla Firefox, SeaMonkey, other Mozilla-based web browsers and Google Chrome, written and maintained by Giorgio Maone, an Italian software developer and member of the Mozilla Security Group. Features Active content blocking By default, NoScript blocks active (executable) web content, which can be wholly or partially unblocked by allowlisting a site or domain from the extension's toolbar menu or by clicking a placeholder icon. In the default configuration, active content is globally denied, although the user may turn this around and use NoScript to block specific unwanted content. The allowlist may be permanent or temporary (until the browser closes or the user revokes permissions). Active content may consist of JavaScript, web fonts, media codecs, WebGL, and Flash. The add-on also offers specific countermeasures against security exploits. Because many web browser attacks require active content that the ...

Linux
Linux ( or ) is a family of open-source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically packaged as a Linux distribution, which includes the kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name "GNU/Linux" to emphasize the importance of GNU software, causing some controversy. Popular Linux distributions include Debian, Fedora Linux, and Ubuntu, the latter of which itself consists of many different distributions and modifications, including Lubuntu and Xubuntu. Commercial distributions include Red Hat Enterprise Linux and SUSE Linux Enterprise. Desktop Linux distributions include a windowing system such as X11 or Wayland, and a desktop environment such as GNOME or KDE Plasma. Distributions intended for ser ...

Object (computer Science)
In computer science, an object can be a variable, a data structure, a function, or a method. As regions of memory, they contain value and are referenced by identifiers. In the object-oriented programming paradigm, ''object'' can be a combination of variables, functions, and data structures; in particular in class-based variations of the paradigm it refers to a particular instance of a class. In the relational model of database management, an object can be a table or column, or an association between data and a database entity (such as relating a person's age to a specific person). Object-based languages An important distinction in programming languages is the difference between an object-oriented language and an object-based language. A language is usually considered object-based if it includes the basic capabilities for an object: identity, properties, and attributes. A language is considered object-oriented if it is object-based and also has the capability of polymorphism, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ruby On Rails
Ruby on Rails (simplified as Rails) is a server-side web application framework written in Ruby under the MIT License. Rails is a model–view–controller (MVC) framework, providing default structures for a database, a web service, and web pages. It encourages and facilitates the use of web standards such as JSON or XML for data transfer and HTML, CSS and JavaScript for user interfacing. In addition to MVC, Rails emphasizes the use of other well-known software engineering patterns and paradigms, including convention over configuration (CoC), don't repeat yourself (DRY), and the active record pattern. Ruby on Rails' emergence in 2005 greatly influenced web app development, through innovative features such as seamless database table creations, migrations, and scaffolding of views to enable rapid application development. Ruby on Rails' influence on other web frameworks remains apparent today, with many frameworks in other languages borrowing its ideas, including Django in Pyt ...

Disk Storage
Disk storage (also sometimes called drive storage) is a general category of storage mechanisms where data is recorded by various electronic, magnetic, optical, or mechanical changes to a surface layer of one or more rotating disks. A disk drive is a device implementing such a storage mechanism. Notable types are the hard disk drive (HDD) containing a non-removable disk, the floppy disk drive (FDD) and its removable floppy disk, and various optical disc drives (ODD) and associated optical disc media. (The spelling ''disk'' and ''disc'' are used interchangeably except where trademarks preclude one usage, e.g. the Compact Disc logo. The choice of a particular form is frequently historical, as in IBM's usage of the ''disk'' form beginning in 1956 with the " IBM 350 disk storage unit".) Background Audio information was originally recorded by analog methods (see Sound recording and reproduction). Similarly the first video disc used an analog recording method. In the music indu ...

Memory (computing)
In computing, memory is a device or system that is used to store information for immediate use in a computer or related computer hardware and digital electronic devices. The term ''memory'' is often synonymous with the term ''primary storage'' or ''main memory''. An archaic synonym for memory is store. Computer memory operates at a high speed compared to storage that is slower but less expensive and higher in capacity. Besides storing opened programs, computer memory serves as disk cache and write buffer to improve both reading and writing performance. Operating systems borrow RAM capacity for caching so long as not needed by running software. If needed, contents of the computer memory can be transferred to storage; a common way of doing this is through a memory management technique called ''virtual memory''. Modern memory is implemented as semiconductor memory, where data is stored within memory cells built from MOS transistors and other components on an integrated circui ...

Method Stub
A method stub or simply stub in software development is a piece of code used to stand in for some other programming functionality. A stub may simulate the behavior of existing code (such as a procedure on a remote machine; such methods are often called mocks) or be a temporary substitute for yet-to-be-developed code. Stubs are therefore most useful in porting, distributed computing as well as general software development and testing. An example of a stub in pseudocode might be as follows: temperature = ThermometerRead(Outside) if temperature > 40 then print "It is hot!" end if function ThermometerRead(Source insideOrOutside) return 28 end function The above pseudocode utilises the function , which returns a temperature. While would be intended to read some hardware device, this function currently does not contain the necessary code. So does not, in essence, simulate any process, yet it ''does'' return a legal value, allowing the main program to be at least partia ...
